		PRODUCTIVITY Speed and efficiency of assembly ERGONOMICS Relationship between process and personnel RELIABILITY Frequency and cost of maintenance and repair QUALITY Adherence to engineering specifications

PERQ^SM- The winning formula in the race... not only with your competition, but with yourself to efficiently produce the highest quality product, ergonomically, and at the lowest possible cost. AIMCO and our suppliers commit ourselves to improving each element of the PERQ^SMformula: Productivity, Ergonomics, Reliability, and Quality. The PERQ^SMformula, combined with AIMCO's integrated product groups and industry experience, enables manufacturers and assemblers worldwide to compete in today's competitive global market.
The goal of a competitive manufacturer and assembler is to optimize and balance the four elements of PERQ^SM and as a result increase revenues and reduce costs. Each of the four PERQ^SM elements interacts. Good intentions to increase one or more of the elements and neglect others may have a negative impact on the overall balance and profitability of your assembly operation. A disciplined program using the PERQ^SM formula will increase the level of all four elements. The result, a positive impact on your profitability!

WHICH OF THE ELEMENTS OF PERQ^SM ARE THE MOST IMPORTANT TO YOU? PRODUCTIVITY? Is the tool fast enough? Does it save time or can I produce more? ERGONOMICS? Is the tool lighter? Does it have less reaction? Better balance, easier to hold? RELIABILITY? Does it last long enough? Is it easy to repair? QUALITY? Does it meet my specs? Does it meet my process verification requirements?

Outside of the mechanical constraints of different applications, each manufacturer has unique priorities regarding how to achieve its goals. Most are concerned with four key areas - productivity, ergonomics, reliability, and quality. What is different from person to person is the weight of each component relative to each other. If your company is trying to double its production rate, high speed may be the most important criteria. If your product has a high potential for liability, quality or repeatability may be the deciding factor.	To help emphasize the point, the analogies work for buying a car. Some people may want the fastest car and will look at horsepower and torque ratings. But this sports car will not have very much room and may require more maintenance. A person with a big family is more concerned about cargo room and safety, but understands that he or she won't be burning rubber at the stoplight.
To meet these changing requirements, one needs an assembly solution supplier with the technical expertise and industry know-how to select the right product from their broad array of available solutions. Even the same application assembled by two different manufacturers with different priorities will dictate a unique solution for each one.	PERQ^SM, a system that AIMCO has developed, asks users to choose two of the four parameters as their most important. From those two choices, one can narrow the type and size of tool. this also helps to recognize the trade offs associated with choosing those priorities. A balance is achieved for the best fit for your application.
The following examples show how your priorities play out in applications where both pulse tools and angle nutrunners could be considered. Of course, these recommendations are general in nature and may not apply to your operation. Please contact your AIMCO representative for an individual consultation.


PERQ^SM PRODUCTIVITY AND ERGONOMICS

TOOL CHOICE	Non Shut-off smaller pulse tools over angle nutrunners.
HIGH PRIORITIES
P	Pulse tools are faster on hard and medium joints and provide one hand operation.
E	Choose pulse tool towards higher end of the tool for size and weight; no torque reaction; non shut-off tools are lighter than shut-off tools.


PERQ^SM PRODUCTIVITY AND QUALITY

TOOL CHOICE	Shut-off mid-sized pulse tools over nutrunners.
HIGH PRIORITIES
P	Pulse tools are faster on hard and medium joints and provide one hand operation; perhaps stick to smaller small to mid size pulse tools - lighter tools for higher productivity.
Q	Wants shut-off tools to eliminate operator influence, or even consider controlled pulse tools if documentation or process verification is desired.

PERQ^SM RELIABILITY AND QUALITY

TOOL CHOICE	Angle nutrunners over pulse tools.
HIGH PRIORITIES
R	Angle nutrunners have less frequent day-to-day maintenance and don't require periodic fluid changes.
Q	Angle nutrunners have a shut-off clutch, which is very repeatable, and consider controlled air or DC nutrunners if documentation or process verification is desired.

PERQ^SM PRODUCTIVITY AND RELIABILITY

TOOL CHOICE	Non shut-off larger pulse tools on hard or medium joints over angle nutrunners or small pulse tools. Angle nutrunners on soft joints over pulse tools.
HIGH PRIORITIES
P	Pulse tools are faster on hard and medium joints and provide one hand operation.
R	Choose pulse tools towards high end of the range or Omega/UX over Alpha for longer periods between fluid changes.

PERQ^SM ERGONOMICS AND RELIABILITY

TOOL CHOICE	Non shut-off larger pulse tools or angle nutrunners (depending on torque and joint).
HIGH PRIORITIES
E	Larger pulse tools are still ergonomic compared to many nutrunners. For nutrunner, our UAN's have lesser torque reaction compared to other brands.
R	Larger pulse tools and angle nutrunners will have less frequent maintenance.

PERQ^SM ERGONOMICS AND QUALITY

TOOL CHOICE	Shut-off pulse tools over nutrunners even on softer joints.
HIGH PRIORITIES
E	Choose pulse tools towards low end of the range for weigh; no torque reaction; on soft joints, choose a larger pulse tool being still lighter than nutrunner.
Q	Choose shut-off tools for less operator influence, or consider controlled pulse tools if documentation or process verification is desired.
